Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, and specifically, to a waste gas treatment system for rubber mixing in factories. Background Art

[0002] The rubber mixing process is an essential core link in the rubber industry, usually including multiple steps such as the internal mixer process, the open mill process, the sheeting process, and the molding process. During the rubber mixing process, a large amount of waste gas is generated by internal mixers, open mills, and other related equipment. The waste gas contains dust, volatile organic compounds (VOCs), odor gases, etc., posing a great threat to the environment and the health of operators. Especially with the increasingly strict environmental protection regulations, higher requirements are put forward for the control of waste gas emissions during the rubber mixing process. Therefore, how to effectively treat the waste gas generated in the rubber mixing process and reduce the emission of harmful substances has become an urgent problem to be solved in the current rubber processing industry.

[0003] Existing rubber mixing waste gas treatment systems usually adopt conventional air collection hoods and dust removal equipment. However, these systems often have defects such as low capture efficiency, unreasonable air flow organization, large equipment space occupation, and inconvenient operation. Especially in the internal mixer and open mill processes, due to the strong diffusibility and high treatment difficulty of the dust and waste gas generated by the equipment operation, traditional waste gas treatment methods often fail to meet the requirements of efficient capture and purification. At the same time, existing air collection devices often leak due to improper air flow control during use, or the service life is shortened or the equipment is damaged due to improper selection of equipment materials. In addition, the waste gas generated during the rubber mixing process may also contain flammable and explosive organic components. Therefore, the anti-static and flame-retardant properties of waste gas treatment equipment are also important considerations in the design. Summary of the Invention
